At the moment, I've got:
I will abandon him this time around, as I usually do. I plan on using Omastar for a water-type this time around, who I've never used in this game before. He'll be gone upon getting Omanyte.
I mostly have been using her for temporary purposes, and she will most likely be abandoned eventually.
I'm not sure how long I'll continue to use him. My experience with him in the past is that he's good during the early stages of the game, but nearly useless against the Elite Four, except to laugh at my rival's Venusaur. However, I put more effort into getting and training this Beedrill than I did last time, so maybe I'll give him another chance.
I've used Fearow a few times before... This is the first time I'm using a female one though. I haven't used it in a long time, so I figured I'd try it again. Not sure if I'll stick with her the whole time though.
My... third naughty-natured pokemon. I'll replace Bite with Shadow Ball as soon as I can. This is my first time using any Eeveelution, as I've never cared for any of them, but Flareon seems alright.
I'll update upon having made more progress.
My team is now:
I've still got him here. I think I won't be teaching him Sludge Bomb because it'll become useless when I transfer him into the fourth gen, where he can learn Poison Jab.
Not sure of whether to replace Secret Power with Return yet. It's not very good in-game because Normal isn't the most useful type. Everything has weaknesses, so I may as well exploit those instead.
It's a great and underrated pokemon.
-Hidden Power Fire
I had to pick between this Exeggutor and a Modest one without Hidden Power Fire, so I picked this one. It probably wouldn't have made much of a difference since I have Flareon with Overheat, but Leech Seed and Sleep Powder aren't so helpful either. So far, the speed reduction from the Quiet nature hasn't been an issue yet either.
Only the first two moves are useful for right now. The second two may become helpful when I decide to transfer him into fourth gen.
